1- This feature is simply selected scenes from the film so while the access is exclusive, the actual content is present on every release.
2- This release also comes with the 2016 Re-release Bluray disc with all the same features found on that release.
3- Although not separately available, these scenes can be watched in the context of the film via the Extended Cut version on this release.
4- The 10th Anniversary Edition of The Da Vinci Code has a very similarly named feature that covers a lot of the same subject matter but is not exactly the same.
5- The packaging advertises two features named that seem to point to this single feature. Both "A First Look at Inferno" and "Legacy of Landon" are apparently this lone feature.
